Application inea june 26, 191e.l serial No. 105,520)` F ig. 5 is a detail justable clamp hubs. j

VIn these drawings l0 indicatesV a pair of end frames suitably connected together -withbearings 1l formed at their upper ends in which a main shaft 12 is jouinaled." A keyway extends the fulllength of the shaft 12, and' a number of clamp hubsl3 are'slidably fittedA on the shaft between the bearings solas to be adj ustable and are `provided with set-sciew-held keys 11i fitting in the keyway them in their adjusted positions and to compel them to' turn with the shaft. j j l Eaclifc'lamp'hub comprises a disk with a iiangeprojecting at its edge on one face View of one ofthe adthereof, said fiange being notched to receive the ends of thebars of ordinary cabinet inakers clamps l5 which eXtend radially therefrom, there being screws 16 passing through the ends of the bars and into the "lof the disk of thel clamp hub and a retaining ring 17 clamped tothe flange to confine the bars withinV the notches.

fit the driving' end ofthe machine the `ma`in shaft 12 extends beyond the bearing land has a gear wheel 18 fixed thereon and lmeshing with a pinion 19 `ca countershaft 20 journaled `in bearings formed byV a bracket2l whichis secured to the end frame. This countershaft 20 carries a fixed pulley 22 anda loose pulley belt` (not shown) with any suitable driving 'A belt, shifter is provided for changing the belt from one pulleyito the other, and

rried by` a aiidconnected by a consists of a sliding rod 2d loosely mounted inthe ends of bracket arms 25 which project froin the bracket 21.

Belt` engaging on the hrod 24 are adapted to have the belt passbetween them so that they will shift it from one pulj ley tothe other as` the rod 24C slides from `oneposition to another.` The belt shifter is normally held in the position shownin Figs.

The pull of the Von to engage rollers on the ends of levers 34 which are fulcrumed at 35 to the end `frames and have their lower ends connected by links 36 with a U-shaped supporting frame 37 pivotally mounted at its ends to lugs 38 .projecting from the end frames. Coil springs 39 connect the supporting frame 37 Vwith the end frames l() to noiinally hold the supporting frame in position to have one series 0f work clamps rest thereon. The

yaction of the cam teeth of cams 32 when the machine has been set in motion by shifting the driving belt to the fixed pulley is to teeth from the position shown in full lines in Fig. 4 to the position shown in dotted lines, thereby swinging the levers 34 and moving the supporting frame 37 out of the range of the work clamps.

As soon as the shaft has rotated in the direction of the arrow a: distance equivalent to one step in -the operation of the machine the springs 39 `return the supporting frame 37 to its operative position, the rollers 33 dropping between the cam teeth again. 1n this posi- .tion of the supporting frame 37 the work clamps, which during the turning movement of the shaft were carried past the position of the supporting frame, are adapted to rest thereon while the operator releases glued work. The clamps are then tightened again and the machine set in operation by pulling on the cable 30.

`The driving connection for the machine is automatically thrown out of operation as soon as the machine has advanced one step.

A For this purpose the cam 32 at the driving end of the machine is provided with laterally. projecting cam teeth -40 which engage with the short end of a lever 41 which is pivotally mounted on the end. frame and A .has a yoke at its longer end engaging a pin through the belt shifting rod 24. Thus at the proper time the belt shifter which is being held on the tight pulley 32 by the operator pulling on the cable 30 is thrown to the. loose pulley 23 by one of the cam teeth j u40 engaging the lever 4l and swinging it to the position shown in Fig. 3.

With the glue clamp of this invention the by Letters Patent is:

Asupported shaft hubs comprising Hanged disks fitting on the the work and reoperator may quickly remove the work from the clamps resting on the supporting frame 37 and replace it with freshly glued work, the position of the clamps being such as to facilitate this operation. As soon as the clamping screws have been tightened he pulls upon the cable 30, thereby shifting the belt to the fixed pulley and causing the ma- -chine to be set in motion, turning the shaft to lift the work which has just been placed in the clamps and. bringing the next row of wood clamps into position. The supporting frame 37 is automatically moved out of the way of the approachingwood `clamps `and returned to its operative positionV beneath the latter bythe action of the teeth of cam 32 against the rollers 33. The operation of theV driving mechanism is automaticallyA dis-V continued by the action of thecam teeth 40 throwing the belt shifter sofas to move the belt onto the loose pulley. The operation is repeated and by the time the work has madethe complete circuit around the machine it is ready to be removed therefrom, making the operation continuous.

lThe clamp hubs being adjustableon the shaft adapts the machine for work of various sizesand enablesthe clamps to be applied at the desired points.

What 1 claim as new and desire to secure "1. A glue clamp,

having a keyway, clamp shaft and having keys extending into the keyway, means for locking the disks in their adjustments on fthe shaft, there being notches in the flanges of the disks, wood clamps with their ends fitting inthe notches and bolted to the disks, and a'retainingring secured to the flange of the disk to confine the wood clamps in thenotches thereof.

2. A glue clamp, comprising end frames, a shaft journaled therein, wood clamps mounted radially on the shaft, cam teeth carried by the shaft, means forturning the shaft,fhand operated meansV for starting the turning means in operation, and a lever adapted to be engaged by the cam teeth for stopping the turning meanswhen the shaft is turned through an angle corresponding with the angle between the wood clamps.

3. A glue clamp, comprising end frames, a shaft journaled therein, wood 'clamps mounted radially on the shaft, a gear wheel on the shaft, a'countershaft having a pinion meshing with the gear wheel, fixedand loose pulleys on the countershafna belt shifter, hand controlled means for moving the belt shifter toward the fixed pulley, camteeth .on

the shaft,and a lever engaged thereby for moving the belt shifter towardthe loose pulley.

4. A glue clamp, comprising end frames,

comprising a suitably ioo the lixecl pulley, a

a shaft journaled therein, Wood clamps mounted radially on the shaft, a, gear Wheel on the shaft, a countershaft having a pinion meshing With the gear Wheel, fixed and loose pulleys on the countershat, a belt shifter, a hand operated cable connected with the belt shifter for moving it toward Weight having conneotion With the belt shifter for moving it toward the loose pulley, earn teeth on the 10 shaft, and a lever engaged thereby for moving the lbelt shifter toward the loose pulley. In testimony whereof I aHX my signature in presence of two Witnesses.
